PRIMARY FLIGHT DISPLAY
Navigation Source
NOTE: OBS is only available with the active flight
plan leg, when navigating under GPS.
The HSI can display two sources of navigation: GPS
or NAV (VOR, localizer, and glideslope). In GPS mode,
the flight plan legs are sequenced automatically. Enabling
OBS mode suspends auto sequencing of waypoints, but
retains the current “active-to” waypoint as the navigation
reference even after passing the waypoint. When OBS is
disabled, the GPS returns to normal operation, with au-
tomatic sequencing of waypoints. OBS mode also allows
the pilot to set the desired course TO/FROM a waypoint.
Color indicates the current navigation source: magenta
(for GPS) or green (for VOR and LOC). As the pilot cross-
es the MAP, “SUSP” appears on the HSI in place of “OBS”
and the
OBS softkey (now) reads “SUSP”, indicating that
automatic sequencing of approach waypoints is suspend-
ed at the MAP. The following yellow annunciations may
appear on the HSI:
• INTEG – RAIM not available
• WARN – GPS detects position error
To change between navigation sources:
1. Press the
CDI
softkey to change from GPS to
VOR1 or LOC1. This places the cyan tuning box
over the NAV1 standby frequency in the upper
left corner of the PFD.
2. Press the CDI softkey again to change from
VOR1 or LOC1 to VOR2 or LOC2. This places
the cyan tuning box over the NAV2 standby
frequency.
3. Press the
CDI
softkey a third time to return to
GPS.
To enable/disable OBS mode while navigating
with GPS:
1. Press the OBS softkey to select OBS Mode.
2. Turn the small CRS knob to select the desired
course TO/FROM the waypoint.
3. Press the
OBS
softkey again to return to normal
operation.
